Recently, there have been increased much concerns about repair and rehabilitation works for aged concrete structures. In particular, it is known that due to repeated overburden vehicle there are significantly increasing number of aged concrete bridge slabs, which are strongly needed to construct and rehabilitate by innovative construction method. The objective of this research is to develop the new construction method of concrete slab in bridge structure, which can contribute to minimize the traffic congestion during the repair and rehabilitation works of aged concrete slab, and can also sufficiently assure the quality through the minimization of in-situ works at the site. I-beams with punch holes, which are substituted instead of main reinforcing steels in concrete slabs, will be manufactured in accordance with the specification in the factory. and will be preassembled into the Panel. After erecting the preassembled panels in the site, concrete will be poured into the slab panel. This research is to investigate physical properties of I-Beam with punch holes itself through static and fatigue test with rational numerical analysis Finally this research is to suggest reformed I-beam through the numerical analysis.

Recently, there are increasing much concerns about repair and rehabilitation works for aged Concrete Structures which had been constructed on around the 1970's for rapid economic growth in Korea. In particular, it is believed that there are many aged concrete slabs for Highway bridges in these days. Thus new construction method of concrete slabs are strongly needed to minimize the traffic congestion during the repair works. The objective of this research is to develop the new constructional method of concrete slab in bridge structure, which can contribute to minimize the traffic congestion to be occurred during the repair and rehabilitation works of aged concrete slab, and can also assure the reliable quality through the minimization of in-situ works at the site. I-beams with punch holes will be manufactured in accordance with the specification in the factory, and will be preassembled into the panel. After erecting the preassembled panels in the site, concrete will be poured into the slab panel. This research is to investigate physical properties of I-Beam with punch holes itself, and then to investigate structural properties of assembled I-Beam panels through static and fatigue test, of which result can be utilized for the development of the new constructional method for concrete slab in bridge structure.

Recently, there have been increased mush concerns about repair and rehabilitation works for aged concrete structures to keep up with rapid economic growth in Korea since the early 1970's. In particular, it is believed in these days that there are significantly increasing number of aged concrete bridge slabs, which are strongly needed to construct and rehabilitate by innovative construction method. The objective of this research is to develop the new construction method of concrete slab in bridge structure, which can contribute to minimize the traffic congestion during the repair and rehabilitation works of aged concrete slab, and can also sufficiently assure the quality through the minimization of in-situ works at the site. I-beams with punch holes, which are substituted instead of main reinforcing steels in concrete slabs, will be manufactured in accordance with the specification in the factory, and will be preassembled into the panel. After erecting the preassembled panels in the site, concrete will be poured into the slab panel. This test is to investigate physical properties of I-Beam with punch holes itself, and then to investigate structural properties of assembled I-Beam panels through static and fatigue test, of which can be utilized for the development of new construction method of concrete slab in bridge structure.

The first objective is find out some life styles on the aged by the actual condition of the daily living activities in old people's home and recuperation facilities. The second objective of this study is to clarify the living behavior patterns of the aged who are under recuperation and living by behavioral places. The thorough investigation and observation works were made to them from the view points of daily living behaviors and activities of the recuperating aged. This article discusses about the basic characteristics of the aged and the actual condition of the daily living activities of the aged in old people's home and recuperation facilities.

The present situation of Korea already shone various symptoms of the aged society, and many kinds of data reported by the National Statistical Office demonstrate those facts. However, to my regret, sufficient efforts for aged workers are not taken in the area of industrial safety. In this research, work arrangement and industrial accidents of middle-aged and aged workers over last 5 years were analyzed. According to research results, proportion of industrial accidents involved middle-aged and aged workers was as high as 40%, and that of aged workers alone was so high as 25%. In addition, proportion of accidents were higher than that of worker population f3r aged wetters. Considering ages, it was demonstrated that as workers get older, mean number of accidents shows the tendency of going higher, and that as years go by, mean lost work-days are increasing regardless of age group. Main accident types were Fall followed by Slip, and Work-Related Disease, furthermore proportion of Slip was highest than any other types for aged workers. Based upon these results, it was emphasized thai careful attention should be paid to functional characteristics of aged workers, and that modification of accident prevention policy would be necessary.

Purpose: This study was performed to identify the meaning of life experience following suicide attempt among middle-aged men. Methods: A qualitative research design was adopted using van Manen's hermeneutic phenomenological approach. The participants were six middle-aged men who had attempted suicide at least one time. Data were collected in 2013 through in-depth interviews. Individual interviews were recorded; and literary, art works and phenomenological literature were searched to identify the meaning of the experience. Results: The five essential themes of the life experience of middle-aged men who attempted suicide were 'Bitter reality confronted again', 'Anger buried deep inside', 'Broken family, inescapable fetters', 'Blocked relationships, closed world' and 'A step towards a new life'. Conclusion: The meaning of lived experience found in this study provides deep insight into the experience following suicide attempt in middle-aged men and crucial information to give directions to appropriate support and nursing interventions.

The purpose of this study is to clarify the charactersitics of the social behaviors on the aged by the actual condition of the daily living activities in recuperation facilities. This paper tries to clarify the relationship between the social behaviors of the aged and the places in recuperation facilities. The thorough investigation and observation works were made to them from the view points of daily living behaviors and activities of the recuperating aged. The surveys on the day-time behaviors of residents(71 persons) were carried out in 4 recuperation facilities and 3 special nursing homes.

Purpose: This study was designed to explore and compare the self efficacy, social support, and quality of life between middle-aged Korean and Chinese women. Methods: The sample included 430 (Korean: 220, Chinese: 210) middle-aged women. Study instruments were the Self Efficacy Scale developed by Shere et al (1982), the Social Support Scale modified and based on Interpersonal Support Evaluation List (ISEL) developed by Cohen and Hoberman (1983), and The Quality of Life Scale (SF-36) developed by Ware and Book (1981). Data were analyzed by SPSS/WIN 16 version. Results: Korean women reported more self efficacy and better quality of life than the Chinese women. The quality of life scores between middle-aged Korean and Chinese women showed a statistical significant difference. Self efficacy and quality of life scores reported by middle-aged Korean and Chinese women were below the reported standards of the instruments. In contrast to the other scores, Chinese women reported more social support than Korean women. Conclusion: The findings add to the body of literature about Chinese and Korean middle aged women. Additional research is needed to explain the differences among the two groups but the findings can inform the practicing nurse who works with these populations.
